Arkansas Rice: Managing Hydrogen Sulfide Toxicity, AKA

It may be time for you to start scouting for root-related problems to relieve or rescue your rice before it is late. Start scouting 2 or 3 weeks after a permanent flood is established. As shown in Fig. 1, color differences in rice roots from a bar ditch or bay (left) with roots from a levee (right), respectively, are indicators of the disorder

Minimum levels of atmospheric oxygen from fossil tree

In summary, emerging plants need to initiate new roots, whereas mature plants need to constantly renew their root systems when old roots are lost to disease or consumed by fauna. How atmospheric p O 2 relates to COPE and long-term plant survival depends on the characteristics of the soil, at least for plants that rely on soil-air O 2 for root

PDF Water Movement in Strawberry Beds

all beds, a blue indicator dye was injected to follow the path of water in the soil. At the end of each irrigation treatment, beds were dissected both lengthwise and crosswise to determine where water had moved. The distance that the dye moved downward both lengthwise and crosswise was measured. Calculations were made to determine percent

Volatile organic compounds emitted by Trichoderma species

Exposed tomato plants also displayed significant increase in plant biomass, larger plant size, and increased lateral root development. Previously, we showed that Trichoderma -volatile induced growth promotion in Arabidopsis was dependent on the duration of exposure [ 25 ] and that early removal of the fungi lead to loss of growth promotion.

Fenugreek Benefits and Side Effects for Men | Fitness Donkey

This holds true for grown men or for children. The real potential side effects show up when Fenugreek is taken in medicinal amounts (i.e., significantly higher amounts than in the average diet) for periods of up to six months. These include "diarrhoea, stomach upset, bloating, gas, and a "maple syrup" odor in urine." (source WebMD).

Ecological succession - AccessScience from McGraw-Hill

The late establishment of broomsedge in the succession is dependent not on changes brought about by earlier colonists but on the life history of the plant. After broomsedge, shortleaf pine invades the herb community. Pine seeds require mineral soil and minimal root competition to become established, and the seedlings are not shade-tolerant.

Plant root and mycorrhizal fungal traits for understanding

Of some traits we already know that they relate to soil aggregation propensity: using correlational approaches (path analysis) to exploit existing environmental gradients in landscapes, coarse-level indicators such as root biomass (or often root length) and mycorrhizal fungal hyphal length in soil have been identified as significant

Evaluation of Bread Wheat (Triticum aestivum L.) Genotypes

The current study was planned to identify drought tolerant bread wheat genotypes based on physiological and yield traits. In this context, a set of 12 genotypes (Sarsabz, NIA-Sundar, NIA-Amber, Sassui, Khirman, Marvi-2000, NIA-Sarang, Kiran-95, NIA-Sunheri, Bhittai, Bathoor-08 and Tatara) were evaluated under normal and water stress conditions.

Evapotranspiration and the Water Cycle

Evapotranspiration is the sum of evaporation from the land surface plus transpiration from plants. The typical plant, including any found in a landscape, absorbs water from the soil through its roots. That water is then used for metabolic and physiologic functions. The water eventually is released to the atmosphere as vapor via the plant's

Coarse and fine root plants affect pore size distributions

We demonstrated that plant roots essentially conditioned soil pore properties via pore stabilization, macropore formation upon coarse root penetration and pore space heterogenization by dense fine root growth. Pore stabilization was obtained by root systems with a minimum density higher 0.5 % of soil pore volume occupied by plant roots.

Data Structure and Algorithms - Tree

Root − The node at the top of the tree is called root. There is only one root per tree and one path from the root node to any node. Parent − Any node except the root node has one edge upward to a node called parent. Child − The node below a given node connected by its edge downward is called its child node.

Feedstock characterization, process conversion and fuel finishing are the building blocks of biodiesel production. Of the three, feedstock characterization is usually underestimated. The lack of depth in the understanding of feedstock's impact on the business plan has lead to challenges that might have been avoided for smaller scale producers.
